In our latest work on the Allegro project, we applied lexicographic optimization to tackle complex combinatorial problems involving conflicting objectives like cost, latency, and availability.
Rather than optimizing all objectives at once, lexicographic optimization solves them sequentially, incorporating the optimal value of one as a constraint for the next. This approach reveals critical trade-offs and synergies across different objective priorities.
đź“Š We explored all possible orderings of the key objectives and normalized the results to compare their impact. A few highlights:
- Prioritizing cost still maintains availability above 90%, showing a natural alignment between the two.
- Optimizing for availability first results in only a 3–5% increase in cost when cost is handled second or third—demonstrating a graceful trade-off.
By merging storage and retrieval metrics into two compact objectives—latency and cost—we simplified the analysis while retaining key system dynamics.
🔄 The results underscore how sequencing priorities can significantly influence outcomes in multi-objective environments. This method offers a valuable lens for designing systems where trade-offs are inevitable but can be navigated smartly.
đź’ˇ Looking ahead, this work opens new doors for more nuanced decision-making frameworks in operations research, supply chain optimization, and intelligent storage systems.
